Circinaria pakistanica sp. nov. is described from the Himalayan moist temperate forests in Pakistan. The morphology, chemistry and ITS sequence support its distinction from other species of this genus. The taxon is characterised by a whitish to blackish grey thallus, greyish white epruinose apothecia, flat to slightly concave areoles, a hymenium 110-200 ?m high, large ascospores (22-38 ? 18-32 ?m) and the absence of pycnidia; it also differs from related species in the ITS region.

Xanthium spinosum is a cosmopolitan annual herb used in traditional medicine worldwide. Although known from ethnobotanical studies, the species is scarcely investigated from the aspects of phytochemistry and biological activity. Therefore, the phenolic composition and biological activity of X. spinosum were examined. Plant specialised metabolites (phenolics) extracted from the roots, leaves and fruits with dichloromethane:methanol (1:1) were analysed by liquid chromatography mass spectrometry (LC-MS). In total 10 phenolic compounds were identified and quantified. Six compounds were common to all the extracts. Chlorogenic acid was the most abundant constituent in all the extracts (4.262 mg/g in the fruit extract, 0.820 mg/g in the leaf extract, and 0.540 mg/g in the root extract). The biological activity (antimicrobial and antibiofilm) of the extracts was tested against 12 microfungi and 12 bacterial strains by the microdilution method. All the extracts exhibited moderate antimicrobial and antibiofilm activity and inhibited the growth of most of the examined microorganisms. The obtained results indicate the potential role of the tested extracts in pharmacy and medicine.

Polyfloral honey samples from Bulgaria were subject to parallel analyses of their botanical origin and composition using traditional melissopalynology, DNA barcoding based on the plastid rbcL gene and NMR analysis. The obtained datasets were compared with each other to evaluate the information capacity of the applied experimental methods. The results from the melissopalynological and DNA-barcoding studies demonstrated a significantly higher resolution of the latter, revealing the presence of pollen from a total of 17 plant families, 21 plant genera and 5 plant species in comparison to pollen from only 7 plant families, 3 plant genera and 4 plant species identified by melissopalynology. The higher resolution of DNA barcoding allows a more detailed characterisation of the diet and foraging preferences of honey bees, including foraging on plant species growing in lower abundance in the area. The comparison of the quantitative data on floral honey composition for several plant genera and species reveals significant differences between the relative abundance of the pollen grains estimated by melissopalynological analysis and the relative abundance of rbcL clones in rbcL libraries determined after DNA barcoding. All three applied methods confirm the polyfloral botanical origin of the analysed samples and support routine NMR use for the assessment of the floral origin of honey.

Rhododendron fortunei (Ericaceae) possesses valuable horticultural and medicinal values. However, the genomic information on R. fortunei is very limited. In this study, the complete chloroplast genome (cp) of R. fortunei was assembled and annotated, SSR loci were characterised, comparative genomic analysis was carried out, and phylogenetic research was also performed. The results showed that the R. fortunei cp genome was of a typical quadripartite structure (200,997 bp). The lengths of the large single copy region (LSC), the inverted repeat regions (IR), and the small single copy region (SSC) were 109,151 bp, 2,604 bp, and 44,619 bp, respectively. A total of 147 unique genes were identified, including 99 protein-coding genes, 42 tRNA genes, and 6 rRNA genes, respectively. Leucine (11.51%) and cysteine (1.15%) were the highest and lowest representative amino acids, respectively. The total of 30 codons with obvious codon usage bias were all A/U-ending codons. Among the 77 simple sequence repeats, the majority were mononucleotide A/T repeats located in the intergenic spacer region. Five gene regions showed high levels of nucleotide diversity (Pi > 0.03). The comparative genome analysis revealed 7 hotspot intergenic regions (trnI-rpoB, trnTrpl16, rpoA-psbJ, rps7-rrn16, ndhI-rps16, rps16-rps19, and rrn16-trnI), showing great potential as molecular makers for species authentication. Expansion and contraction were detected in the IR region of the R. fortunei cp genome. In the phylogenetic tree, R. fortunei was closely related to R. platypodum. This research will be beneficial for evolutionary and genetic diversity studies of R. fortunei and related species among the Ericaceae family.

Determining the mechanisms underlying tolerance to osmotic stress and salinity during the germination period is an essential task in order to improve agricultural production in arid and semi-arid areas. In this work, the seeds of bread and durum wheat cultivars were treated with different concentrations of polyethylene glycol (PEG)-6000 and NaCl for 1 week, and half-maximal inhibitory concentrations (IC50) of germination were calculated. The seeds were then exposed to IC50 values of NaCl and PEG-6000 for 2 days in order to assess their physiological and biochemical properties. Alpha and beta amylase enzyme activities, the reducing sugar, total sugar, proline, protein, and H2O2 contents, and DPPH radical scavenging activity of the seeds were determined by spectrophotometric methods. The results showed that the bread wheat seeds had a much higher tolerance to excess salt and osmotic stress than the durum wheat seeds. In particular, the average IC50 value of NaCl for the bread wheat cultivars was almost twice that for the durum wheat cultivars. The imbibition test revealed that the water uptake capacity of the seeds did not explain the difference in tolerance to these stress conditions. On the other hand, the bread wheat seeds exhibited constitutively higher proline, total sugar, and H2O2 contents as well as antioxidant capacity compared to the durum wheat seeds (p < 0.05). In conclusion, the current findings suggest that the interplay of oxidative metabolism and compatible solutes may contribute to improving germination tolerance under water deficit and salinity conditions in wheat.

The Caucasian oak (Quercus macranthera), a native tree of Western Asia, typically grows at high altitudes where the effects of climate change are particularly notable. We analysed the climatic determinants of the current distribution of Q. macranthera and assessed the redistribution of areas suitable for this species as a consequence of climate change. We described the current range of distribution and predicted the potential geographical distribution of the Caucasian oak using species distribution models and five algorithms from two Shared Socio-Economic Pathways (SSPs: SSP 1-2.6 and 5-8.5) for the years 2035, 2055, and 2085, which are based on two General Circulation Models (GCMs). The Random Forest algorithm most accurately described the current distribution of Q. macranthera. SSP 1-2.6 and SSP5-8.5 predicted a pronounced contraction of the highly suitable habitat for the Caucasian oak due to the increase in temperatures and changes in seasonal precipitation dynamics, that more intensive climate change could lead to a greater loss of highly suitable habitats, and that the populations of Q. macranthera could survive only in the Alborz Mountains (northern Iran) and in the Great Caucasus Mountains. Our work helps to establish conservation strategies for species monitoring in order to minimise the potential impacts of climate change.
